Product Information
Full details
The Urth ND4 2-Stop Lens Filter is an essential tool for photographers and videographers seeking precise light control without sacrificing image clarity. It is ideal for those who need to manage exposure in bright conditions or wish to employ slower shutter speeds and wider apertures, though users should note that it offers a fixed light reduction rather than the flexibility of a variable ND filter.

FAQs
What does a 2-stop filter mean?
A 2-stop filter reduces the amount of light entering the lens by a factor of 4, or exactly 2 exposure stops.
Can I use a lens cap with this filter?
Yes, the filter is double-threaded, which allows you to attach a standard 46mm lens cap to the front of the filter.
Will this filter cause vignetting?
The ultra-slim design is specifically engineered to prevent vignetting on most standard and wide-angle lenses.
Is this filter compatible with all lenses?
It is compatible with any lens that features a 46mm front filter thread. For other sizes, you would need a step-up or step-down adapter ring.
How do I clean the nano-coating?
Use a gentle circular motion with a clean, dry microfiber cloth. For stubborn smudges, use a small amount of lens-safe cleaning fluid.
Can I stack this filter with a polarizing filter?
Yes, because the filter is double-threaded, you can attach another filter to the front of it.
Troubleshooting
Filter is stuck on the lens
Use a rubber filter wrench to apply even pressure to the outer ring of the filter to loosen it without damaging the glass.
Visible reflections in the frame
Ensure the lens is clean and that there are no additional filters stacked that might be causing internal reflections.
Difficulty threading the filter
Check to ensure the filter and lens threads are free of grit or sand; verify that the thread size is exactly 46mm.

Setup, Compatibility & Care
To install, simply screw the filter clockwise onto the 46mm filter thread of your lens. Ensure it is tightened securely but avoid over-tightening. If you are using a lens hood, ensure it is compatible with threaded filters. For care, use a clean microfiber cloth to wipe the glass. If the filter becomes soiled with water or oil, use a specialized lens cleaning solution sparingly. Store the filter in its protective case when not in use to prevent scratches and dust accumulation.
